Two Parchman inmates are dead in what Mississippi Department of Corrections says are unrelated incidents.

Sunflower County Coroner Heather Burton said the deaths of both inmates “appear to be suicides. Both are under investigation.”

Michael Montrell Norwood, 29, and Milton Craig, 28, were found unresponsive in their single cells in separate buildings at Unit 29.

Norwood was pronounced dead at 6:17 a.m. Monday. He was serving a total of 15 years for three crimes in Panola County. His sentence began on Feb. 23, 2014, for selling marijuana, shooting into a dwelling, and aggravated assault.

Craig was pronounced dead at 1 p.m. He was serving a 10-year sentence for armed robbery in Hinds County. His sentence began on Feb. 26, 2011.

Burton said both inmates appear to have hanged themselves and that the deaths are being investigated by the Corrections’ Investigative Division.

“They were in cells by themselves,” she said. “It doesn’t appear to be any foul play at this time.”

It's unclear if there were any drugs or other outside influences. The cause and manner of death of each inmate are pending an autopsy and investigation.
